Project: Bachelor thesis BiologyAuthor: Roman BeukemaInstitute: Universiteit van AmsterdamSupervision: drs. Nienke BeetsDate project: 29-03-2021/28-06-2021>Description<These measurements include the raw data on the petiole and lamina length and width of Plantago major populations growing within 3 different habitat types: an urban city sidewalk (Amsterdam center, Leiden center, Haarlem center), a city park (Vondelpark in Amsterdam, Het Plantsoen in Leiden, Kenaupark in Haarlem) and a nature reserve (Slufter, Duin & Kruidberg, Vegelingsbos). The data was collected between 12-04-2021 and 07-05-2021 by Roman Beukema. The dataset includes both GPS longitude and latitude locations from each sample, as well as the lamina and petiole length and width in millimeters precise.>Note<Due to poor internet connection, only for a limited amount of sampling points at Duin & Kruidberg the GPS coordinates could be determined. These GPS points, where the location could not with accuracy be estimated, are here represented with NA (�not available�).
